GroveLite fair triad — all on the web

Same city rules (buildings + agents + orbit). Each path uses its own 3D stack — no Rust-side Three.js.

1) Keel-TS · Three.js (WebGL)

Keel-TSThree.js CityArena / GroveLite S1

~576 buildings · 200 agents

S2 Heavier city

~1296 buildings · 500 agents

2) Keel-RS · wgpu (WebGPU)

Requires WebGPU (Chrome / Edge). Scene via ?scene=S1|S2|S3.

3) Bevy · engine WebGL2

Large first download (~37MB wasm split into 3 parts). Chrome/Edge recommended.

Fair compare notes

TS path = Three.js specialty (WebGL).
Keel-RS path = raw wgpu specialty (WebGPU).
Bevy path = Bevy render specialty (WebGL2 on web).
Same GroveLite sim rules; visual budgets aligned (boxes, orbit, no shadows v1).
